UMBRELLA-TIP.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed January 16, 1920. Serial No. 351,851.

To all whom it may concern:

Be it known that I, SIMON I. Gonnsrnm, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Umbrella-Tips, of which the following is a specification.

This invention relates to improvements in devices for detachably connecting the margins of umbrella covers to umbrella ribs, and more particularly to ribs of solid cross section. In my application, Serial No. 313,785, filed July 28, 1919, I have shown a device for detachably connecting the margins of covers to umbrella ribs, the device itself being readily detachable from the cover. The attaching devices shown in said application comprise a hollow tip and a solid tapering pin, suited more particularly for use with ribs having tubular ends. In the present invention, the pin is hollow and therefore adapted to fit readily on to ribs having solid ends.

In the accompanying drawing which illustrates my invention,

Figure 1 is a side elevation, taken from the outside of the cover, showing one of the attaching devices in position upon an unibrella rib, the latter being shown in dotted lines- F 2 is a similar view, taken from the inside of the cover, the rib being omitted;

Fig. 8 is a side elevation, taken from the inside of the cover, showing one of the attaching devices upon an umbrella rib;

Fig. 4 is an enlarged view, taken in section on the line 4.4; of Fig. 3; and,

Figs. 5, 6, 7, and 8 are perspective views, showing various forms of the tapering pin or cone.

Referring to Figs. 1 to a, inclusive, of the drawing, a indicates a hollow tip comprising a tubular portion 1, which may be cylindrical but is preferably slightly tapering from its open end to its closed end 2, which latter is preferably globular in form to resemble the tip of an ordinary umbrella rib, wh1ch usually terminates in a small sphere. A hollow tapering pin 6 is adapted to fit, for the greater part of its length, within the tubular tip, as shown in the various figures of the drawing, the base of the pin, however, being of such diameter that it does not enter the tip but projects slightly therefrom, as shown.

In applying the device to an umbrella, the corners of adjacent sections 3 and 4 of the cover are inserted within the tubular tip, and the tapering pin is then pressed firmly into the tip and the end portions of the sections are thereby wedged firmly between the in and the tip. After the sections of the cover have been secured within the tip by the pin, as shown in Fig. 2, the tubular pin is placed over the end of the umbrella rib 5, in which position it is held by the tension of the cloth along the line of the seam between the sections. To detach the cover from the ribs, it is only necessary to grasp the attaching devices and pull outwardly upon them until the hollow pins leave the ends of the ribs. When an attaching device is disconnected from the rib, as shown in Fig. 2, if it is desired to remove the attaching device from the cover, it is merely necessary to grasp the tip a in one hand and the projecting end of the hollow pin in the other, or with a pair of pliers, and pull them apart and this releases the cloth. The facility with which the device may be disconnected from the cloth is an important feature. Separable tips, generally, are secured permanently to the cloth and usually there is a loss of time and injury to the goods by the removal of the tip therefrom, whereas with the device of the present invention the goods are not injured by attaching or detaching the tip and very little time is required for either operation. Thus, if it is necessary to remove a torn or defective section from an uinbrella fitted with the tips of my invention, the cover can be disconnected from the rib and the attaching devices can be disconnected from the cloth in a few moments, when the new section can be applied and replaced on the rib with a minimum loss of time.

The hollow tapering pin may be a plain tapering tube, circular in cross section throughout, as shown in Figs. 1 to a, or it may be modified in various ways as shown in Figs. 5 to 8, inclusive. In Fig. 5, the pin 7) is angular in cross section, the advantages of this angular arrangement being more particularly set forth in my co-pending application above referred to. In Fig. 6, the pin has its base corrugated, as shown at 6, the corrugated portion serving as a means for gripping the cloth, when inserted in the tip, and also affording a roughened surface by which the pin may be grasped when it is desired to pull the pin out of the tip. Where the umbrella cover is composed of a coarse fabric, or fabric that is knotty and not of smooth, even texture, it may be desirable to use a pin such as thepin 6 having its small end slotted, as shown at 7 or a pin such as shown at 6 in Fig. 8, having slots Sat its larger end. Such pins when forced into the tips will yield slightly if the fabric is thick or uneven, and in such eventthe slotted pin may be forced into the tip without difliculty.

What I claim is:

1. Means for attaching covers to umbrella ribs comprising atubular tip adapted to receive the corners of adjacent cover sections, and a hollow conical .pi-n adapted to wedge into the ti and bind said corners therein, said pin a apted to engage over the end of an umbrella rib.

2. Means for attaching covers to umbrella ribs comprising a tubular tip adapted to receive the corners of adjacent cover sections, and a hollow conical pin, having a longitudinally slotted end, adapted to wedge into the tip and bind said corners therein, said pin adapted to engage over the end of an umbrella rib.

In testimony whereof I afiix my signature.

SIMON I. GOLDSTEIN.
